Application filed February 13, 1918. Serial No. 216,847.

ie tudinally, and has for its primary object to provide an improved device ofthis type which. will be simple in construction, inexpensive to manufacture, easily applied to the rail, and which will act to prevent the rail from creeping in either direction; an

, anti-creeping device having this latter char- 'acteristic being desirable for use on single track roads where the traffic runs in opposite directions, or in other situations in which an the rail tends to move sometimes in one direction, and sometimes in the other.

The invention consists in the novel arrangeinents, constructions and combination of parts, hereinafter described and claimed,

for carrying out the above stated object, andsuch other objects as may appear from the following specification.

The invention is illustrated in certain preferred embodiments in the accompanying .80 drawings, wherein Figure 1 is a view in perspective of a rail anchor, constructed in accordance with my invention, applied to a railroad rail;

Fig. 10 is a cross-secti0n taken on line 5510-10 of Fig. 9; and

Referring first to Figs. 1 to 7 inclusive of the drawings, 10 designates a railroad rail and 11, 11 two ad acent cross-ties on which the rail is supported. The rail anchor illustrated in these figures preferably consists of a shoe or rigid member 12, and a yoke member 13, which together embrace thebase flange of the rail and have an interlocking engagement with each other which maintains these members in their operative position on the rail. T he shoe member 12 may be made of any suitable material; preferably it is a malleable casting, and is formed with jaws 14, 14 which fit over one edge of the rail base at points adjacent the crossties 11, 11, respectively. These jaws are preferably made up of an upper lip 15, which referably extends the entire length of the shoe and has its under surface 16 formed with an inclination which corresponds to the taper of the upper surface of the rail base, and with lower lips 17 and 18 at each end of the shoe which extend under the rail base and cal web 19 connects the above mentioned lips together and rigidities the shoe 12 as a whole from end to end. 20, 20* designate tie abutting portions formed at each end of the shoe 12 and which are adapted to bear against the adjacentvertical faces of the cross-ties 11, 11, respectively. The vertical web 19, is preferably curved downwardly as indicated at 21, so as to reinforce the lower portion of the tie abutting portions 20, 20. The yoke 13 is preferably made of spring metal and is formed at one end with a jaw 22 which engages the edge of the rail base 0pposite the shoe 12, and is forn'icd with an angularly disposed hook portion 23, which is forced into a biting engagementwith the upper surface of the rail base when the angiven a slight set or twist, as indicated in Figs. 3 and 7, so that the enlargement 24 will normally stand at a slight angle with relation to the jaw 22. When the shoe 12 and the yoke 13 are in operative position on the rail, the body portion of the yoke adjacent the enlargement 24 extends into a recess 25 formed in the web 19 (Figs.'5 and 26 designates a projection on the web 19 which is cut away as indicated at 26 to provide a supporting shelf adapted to support the lower edge of the yoke. When applying the yoke 13 to its interlocking position with the shoe 12, as indicated in Figs. 1, 2, 4 ant? 5, the yoke is subjected to a torsional strain by twisting the same from its'normal -set position, as indicated in Fig. 3, to the position indicated in Figs. 1 and-2. This twisting operation may be accomplished by any, sultablemeans, such for example, by use of the claw bar or wrench 28 (Fig. 6), which may be applied over the enlargement 24. 29 designates a boss on the wrench which ena es the projection 26 and provides a suitb e fulcrum for the wrench when springing The tendency which the spring yoke has to return to its normal, or twisted condition exerts a spring ressure against the lug 30.

Thispressure prevents vibration of the rail from dislodging the yoke from its seat on the shelf 26, or appreciably lessening its effective grip on the base'flange of the rail. The spring yoke, when applied in operative position, preferably stands at substantially right angles to the shoe 12, so that any longitudinal movement of. the rail in either direction tending to change the angular relation of these members will increase the grip of the device on the rail base.

In the embodiment of the invention illustrated in Figs. 8 to 11 iinclusive, I have shown .a modified form of shoe or rigid member 31 which consists of a, metal bar which engages the upper inclined surface of the base flange A of the rail base,

at each end with t1e engaging lugs 32, 32.

These lugs are preferably formed with shoulders which fit over the vertical edge of the base flange of the rail and are spiked to the top surface of two adjacent ties by means of spikes 33. The bar 31 is provided at the center with a depending flange 34 which is recessed. as indicated at 35 to receive the g a the yoke from its normal position, as lndiand is formed body portion of the. spring yoke, and is provided with a supporting 'she1f36and boss 37 for holding the spring yoke member 13 in its operative position, in substantially.

the same manner as thatdescribed in con.- nection with the device shown in Figs 1 t0 7 inclusive. The web 34 is formed on each side of the recess 35 with inwardly projecting lugs 38 and 39, which extend underneath the rail base and provide a railbase engaging jaw 40 adjacent the spring yoke 13. In other respects, the construction and operation of this device is substantially the same 1.
